Best Online Grammar and Punctuation Checker tools in 2017

grammar check grammarly.com

I am personally using Grammarly as my proofreading tool. Not just only me, more than 4 million people use Grammarly to check their grammatical and spelling errors and correct them instantly.

Business professionals, college teachers, university lectures, bloggers, students, and even professional writers use this powerful grammar check tool to make error-free articles.

Among Grammarly’s sophisticated features, I have found a few key features. Here are some of them.

Key features:

Not only in Microsoft Word program, but Grammarly Addon also supports to all other applications of MS Office as well. (EX: Excell, Access)
  • Check for Content Plagiarism: If you are a blogger just like me, you would know the Google Panda update pretty well. It is a nightmare for websites that have thin and duplicate contents. Google Panda punishes websites that have duplicate and low-quality content. Checking plagiarism for your blog posts is very important as an SEO’s point of view. Even though, I know that I am a genuine article writer, I have practiced myself to check plagiarism of my content in every time I write a new blog post. And I don’t forget to analyze SERP for every time I get a new content idea.

    You can calculate purity (originality) of your content with Grammarly’s plagiarism checker tool.

  • English grammar check: With the ability of test over 250 English punctuation and vocabulary errors, you can turn your errorful article into error-free article very quickly. In General, it takes about 5-10 minutes to correct all grammar mistakes of an article with 2,500 words. Yes, it ultimately depends on your writing style and the number of errors. But, Grammarly can correct all grammar mistakes quicker, unlike other grammar corrector tools. As Google check grammar quality of your articles, you should be aware of the grammatical errorless of your article even if you’re a freelance writer.
  • Vocabulary Enhancement: This feature is especially very useful for content marketers. Do you know the importance of having an article with diversified words?  If your each article is about 1000 words longer, but a few words take 10%-40% portion of that count, is it a good sign of a quality article? Not, right? With Vocabulary Enhancement tool, you can find synonyms and make your dead articles meaty and interesting ones to consume. Vocabulary Enhancement tool will help your blog post to rank for a number of unpredicted keywords higher on SERPs. Just use one time and see how your blog traffic increases over time dramatically.

    A moment of Grammarly suggests synonyms.

Grammarly can be used as an online tool and software that works on your PC, tablet or laptop. There are no differences between these two methods. I have used these both methods. They are simply perfect!

If you are searching an excellent spelling and grammar check tool to correct punctuation and wording errors, I recommend Grammarly tool as I am currently using this tool.

That happens when we lose our perception and our awareness. But, with “Sentence Rephraser” tool, you can check grammar of sentences and adapt to proper language style either to written language or oral language.

As you need a quick solution for your grammar and punctuation mistakes, using an accurate and a robust grammar and punctuation checker tool is the best way to go.

I use Grammarly’s premium version. It checks my grammar and punctuation. Analyze the text and fix my grammar mistakes quickly.

Abhishek Nale

Thanks Chamal

Sienna Eskildsen

Good to know about these spell checkers, I used grammerly free version sometime back and recently i used Ginger, I think this is one of the best spell checker, i need to check others too, will come back again to you with my experience, Thanks

Anuradha Chawla

Hello Chamal

A nice post, at the end. Writing a blog post take times, I love writing, though. However, when it comes to proofreading it, I always get bored and takes time. And that’s where tools like Grammarly or Ginger are used by me.
This is an AWESOME post.
Thanks. 🙂

    Chamal Rathnayaka

    Hello Anuradha,

    Yes, of course I too face your problem. When it comes to proofreading, I too little bit step back. Because it’s boring. However, proofreading is a great way to find errors and missings on article. My best grammar tool for proofreading is Grammarly.

    Thanks for your awesome comment!


Personally, I like Grammarly tool as an online grammar checker. I think this is only the best tool for professional writing. But most of the time I use my combine formula to write something in English. So that is a very interesting formula for me.
However, thanks for sharing your list with us. Hopefully, this list will be more helpful for bloggers, students and freelance writer to write errorless writing.


I mostly use the grammarly addons for chrome to detect and fix grammar error but above shared tools are also great. I think you have missed a most powerful Grammar error detecting tool By SEO Tools Centre which can detect grammar errors up to 26 languages freely.

Oliver Guirdham

I agree with Nicholas. Sorry to be mean Chamal but your advice on these sites would be stronger if your writing was not littered with basic errors. I have been managing large teams of people in India writing for a long time and found to my amazement that none of these programmes deal with the most common and basic errors normally found in Indglish writing. Try typing the sentence ‘The England is better than German army’ into them, which breaks basic rules of how to use articles. None of them pick it up. I don’t understand why these tools can’t pick up these basic issues, as well as more complex style issues, but they don’t, so I have given up on them. Nicholas VirtualWritingTutor.com catches the issue with ‘German army’ but not the problem with ‘the England’ which I think is pretty basic and fixable? I have entered a change request. If you are interested I am happy to test some more text with the typical errors we encounter. If we could remove even 75% automatically it would be a godsend.

    Chamal Rathnayaka

    Oliver, I also admit that my writings are not 100% correct. There are a few reasons for that.

    Yes, NOT any grammar checker tool can fix those common errors. That’s a reason why every programmed application can’t replace for man’s talent, skills.

    Nicholas Walker

    Oliver, I got your suggestion for “the England” and added a rule to cover “the” + 164 countries to the VirtualWritingTutor.com. You can check it. As for what you call “basic rules,” it is amazing the number of basic errors that a native speaking educated human can detect in English– but it takes that human 25 years to develop the ability. To get a computer to detect and correct just a fraction of them has taken me 4 years and 81000 lines of code. I develop the error detection rules for the VWT from the errors in my French speaking college students’ writing in Montreal. If you have insights into “Indglish” errors, please share. I will do my best to catch them with your guidance.

Nicholas Walker

I enjoyed your article and agree with your conclusions. However, what I think you are really looking for is an ESL grammar checker. ESL is “English as a Second Language.” None of these websites target the kinds of errors second language speakers make. They are designed for American college students, not bloggers writing in their second language. I will give you an example from your own article. You wrote this:

As humans, we do lots of flaws. Even you are a professional writer, poet, author or a freelance copywriter; you would make lots of grammatical and spelling errors. If I didn’t use a punctuation checker tool for this article, I wonder if you could understand the text I wrote!

There are at least 5 second language errors in these sentences that first language grammar checkers won’t catch. That’s why as an ESL teacher I always recommend a particular website which is not on your list.

VirtualWritingTutor.com is the only free online ESL grammar checker that will catch second language errors that the other websites miss. Copy/paste the sentences above to see what I mean.

Anyway, thanks for a great article and the useful lists of key features.

Giovanni Bagayas

Thank You for sharing, I badly need this, My grammar sucks really he he 🙂

Sae Kyung

This is one of the best blog that I had ever seen this before. I just love your post. Now-a-days grammar is very important in the English language. I am using Nounplus(dot)net . It is a free Grammar checker. After using this I increased both my grammar and writing skill. Thanks for sharing with us such a wonderful post.

    Chamal Rathnayaka

    Yes Sae, i always use online grammar correction tools to fix my grammatical mistakes. It is very important as one incorrect word can change the meaning of entire article. I didn’t know about Nounplus grammar checker tool. Thanks for let me know about it.

Jason Briggs

Cool post! I like grammark! But apart from grammar and punctuation checking, it is also worth checking for plagiarism. I use this tool , which is perfect for bloggers.
